Protein nameGem-associated protein 5
Protein functionThe SMN complex plays a catalyst role in the assembly of small nuclear ribonucleoproteins, snRNPs, the building blocks of the spliceosome. Thereby, plays an important role in the splicing of cellular pre-mRNAs. Most spliceosomal snRNPs contain a common set of Sm proteins SNRPB, SNRPD1, SNRPD2, SNRPD3, SNRPE, SNRPF and SNRPG that assemble in a heptameric protein ring on the Sm site of the small nuclear RNA to form the core snRNP. In the cytosol, the Sm proteins SNRPD1, SNRPD2, SNRPE, SNRPF and SNRPG are trapped in an inactive 6S pICln-Sm complex by the chaperone CLNS1A that controls the assembly of the core snRNP. Dissociation by the SMN complex of CLNS1A from the trapped Sm proteins and their transfer to an SMN-Sm complex triggers the assembly of core snRNPs and their transport to the nucleus. GEMIN5 acts as the snRNA-binding protein of the SMN complex. {ECO:0000269|PubMed:11714716, ECO:0000269|PubMed:16857593, ECO:0000269|PubMed:18984161}.
Subcellular locationNucleus, nucleoplasm {ECO:0000269|PubMed:11714716}. Nucleus, gem {ECO:0000269|PubMed:11714716}. Cytoplasm {ECO:0000269|PubMed:11714716}. Note=Found both in the nucleoplasm and in nuclear bodies called gems, Gemini of Cajal bodies that are often in proximity to Cajal, coiled bodies. Also found in the cytoplasm.
